A car is moving on a levelled road and gets its velocity doubled.In this process : 1 how would kinetic energy of car changes? 2 how would potential energy

of car will change? 3 how will momentum change ?give reasons PLS FAST


1) KE = (1/2)mv² 
 if v is doubled, then KE becomes 4 times of initial KE
2) PE = mgh 
 as v is increased, g ↓ and hence PE ↓
3) Momentum=mv
 ∵ v is doubled ∴ Momentum also doubles
